Ask an Engineer

MIT engineers and colleagues have developed a soft, flexible gel that dramatically changes its conductivity upon the application of light. This figure shows a soft, stretchable circuit created with a rectangular bar of the gel. A copper electrode is attached to the left. A stylus and associated metal network connects the electrode to three “stations” on the bar. Light has been shone on the first two stations, creating conductivity that turns on each station’s lightbulb. Because the third station has not been exposed to light it is nonconductive and the bulb is off.

Light-activated gel could impact wearables, soft robotics, and more
